OpenVMS VAXDRIV12_U2055 VAX V5.5-2 DUDRIVER ECO Summary

 
NOTE:  An OpenVMS saveset or PCSI installation file is stored
       on the Internet in a self-expanding compressed file.
       The name of the compressed file will be kit_name-dcx_vaxexe
       for OpenVMS VAX or kit_name-dcx_axpexe for OpenVMS Alpha.
 
       Once the file is copied to your system, it can be expanded
       by typing RUN compressed_file.  The resultant file will
       be the OpenVMS saveset or PCSI installation file which
       can be used to install the ECO.

ECO KIT SUMMARY:

An ECO kit exists for DUDRIVER/TUDRIVER on OpenVMS VAX V5.5-2, V5.5-2H4, 
and V5.5-2HF.  This kit addresses the following problems:


Problems addressed in the VAXDRIV12_U2055 Kit:

  o  DUDRIVER does not FLUSH the pending queue of SHADOWING, HBR and
     served  IOs when connection failure routines are entered.  This
     causes a system/cluster hang.


Problems addressed in the VAXDRIV11_U2055 Kit:

  o  These OpenVMS VAX V5.5-2 problem corrections were included in
     the multi-version VAXDRIV04_070 remedial kit.  They are now
     being issued as a V5.5-2 only remedial kit.

     There are no new problem corrections in this remedial kit.


Problems addressed in the VAXDRIV04_070 Kit:  

  o  A PGFIPLHI system crash may occur when the controller is rebooted.

  o  A problem exists with HSJ/HSD30, 40 and 50 controllers where,
     after an event that initiates Mount Verification, a packet 
     acknowledgment will fail to complete.  The controller will 
     report that it is making progress on the command, but will 
     never finish.  This causes all IO to the affected devices to 
     hang.  


Problems addressed in the VAXDRIV02_070 Kit: 

  o  A node may hang due to no quorum after losing its connection 
     to the quorum disk.

  o  DUDRIVER does not log IRP information.


INSTALLATION NOTES:

In order for the corrections in this kit to take effect, the system
must be rebooted.  If the system is a member of a VMScluster, the
entire cluster should be rebooted.
